Application filed September 27, 1909. Serial No. 519,871.

To all whom it may concern:

Be it known that 1, JOHN F. SHEoKLnR, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented cer tain new and useful Improvements in Machines for Making Brick, of which the following is a full, clear, and exact description, reference being had to the annexed drawings.

The object of this invention is to produce a machine of this class which is cheap and simple in construction and which can be more quickly and conveniently operated than other machines of this class heretofore used.

Other objects and advantages of the invention will be set forth in the ensuing description.

Referring to the annexed drawings: Figure 1 is a side elevation of the complete machine, showing the parts in the position inwhich they stand for filling certain molds with material for compression. Fig. 2 is a view similar to Fig. 1, but showing the parts in different position. Fig. 3 is a view similar to Figs. 1 and 2, but showing the parts in still another position. Fig. 4 is a front elevation of the machine, showing the parts in the same position as in Fig. 1. Fig. 5 is a front elevation similar to Fig. 4, showing the parts in the same position as in Fig. 2. Fig. 6 is a front elevation similar to Figs. 4 and 5, showing the parts in the same position as in Fig. 3. Fig. 7 is a plan view of the machine, no parts being shown below the line 8-8 of Fig. 4. Fig. 8 is a sectional view taken on the line 8-8 of Fig. 4, no

parts being shown below the line 99 of said Fig. 4. Fig. 9 is a sectional view taken on the line 99 of Fig. 4, no parts being shown below the line 1010 of said Fig. 4. Fig. 10 is an enlarged sectional view of a portion of the machine, taken on the line AA of Fig. 4, and showing the parts in the same position as in said Fig. 4 and Fig. 1. Fig. 11 is a sectional view similar to Fig. 10, but showing the parts in the same position as in Figs. 2 and 5. Fig. 12 is a sectional view similar to Fig. 10, but showing the parts in the same position as in Figs. 3 and 6.

Referring to the several figures, in all of which like characters of reference designate like parts, the improved machine is provided with a supporting frame-work composed of a cast-metal base 11; round metal columns 12 which are inserted into the four corners of the base 11; and a cap 13 int-o which the columns 12 are securely inserted. A. cast-metal casing 14 is mounted within the framework at about mid height thereof, the columns 12 extending tightly through the corner portions of said casing and supporting it rigidly for the purposes later shown. This casing 14 is divided into compartments or chambers 15 in which the material to form the brick is compressed, there being three such chambers shown in this instance. A fiat yoke 16 is mounted above the casing 14 and adapted to move vertically, the columns 12 of the frame-work passing slidably through the corners of said yoke. The lower face of this yoke 16 is provided with three plungers 17 adapted to enter the press-chambers 15 of the casing 14 as said yoke 16 is lowered. A similar yoke 18 is mounted below the casing 14 and adapted to move'vertically like the yoke 16, the columns 12 of the frame-work passing slidably through the corners of said yoke 18 in the same manner as through the yoke 16. The upper face of this yoke 18 is provided with three plungers 19 which remain entered within the lower ends of the presschambers 15 of the casing 14.

A revoluble shaft 20 is journaled laterally through the lower portion of the framework in bearings 21 which are supported by the columns 12. This shaft 20 is provided inside the frame-work with two eccentrics 22 which are tightly set in the same rotative position on said shaft. This shaft 20 is also provided on the outside of the frame-work with two similar eccentrics 23 which are set tightly on said shaft in a position diametrically opposite the innereccentrics 22. The inner eccentrics 22 of the shaft 20 are operatively connected with and adapted to raise the yoke 18 by connecting-rods 24. These connecting-rods 24 each consist of an upper and lower member 24" and 24 respectively, which telescope together, this arrangement allowing the yoke 18 to be forced upward by revolving the shaft 20, while said yoke 18 may afterward be raised independently of said shaft. The outer eccentrics 23 are provided with upwardly-extending connecting-rods 25 whose upper ends pass through guiding lugs 26 secured to the ends of the casing 14, the upper ends of these connecting-rods 25 being formed into downwardly-inclined hooks 27 adapted to engage projecting lugs 28 on the ends of the upper yoke 16. The upper hooked ends of these connecting-rods 25 are yieldably held in position to engage the lugs 28 by leaf springs 29 which are secured to the ends of the casing 14. For releasing the engagement of these connecting-rods 25 with the lugs 28, for purposes later shown, a lever 30 is pivoted centrally of the upper face of the upper yoke 16, two tl1rustrods 31 being pivoted to said lever on opposite sides of its fulcrum and. passing out slidably through upwardly-projecting integral end portions 16 of said yoke, as best shown in Fig. 8. By moving this lever 30, these thrust-rods 31 are forced outward and release the engagement of the rods 25, the lever the-n drawing the thrust-rods back inward in obedience to a tension spring 32. The upper yoke 16 also has a rod 33 extending tightly through its upwardly-projecting end portions 16*, above the thrust-rods 31, and projecting outward at each end. Each end of this rod 33 is provided with a depending connecting-rod 34, so pivoted thereto that its lower end may swing in a fore-and-aft direction in the rear of the shaft 20, and said shaft is provided with radial arms 35 adapted to engage shoulders 36 on said connecting-rods 34 and lift up thereon to lift the yoke 16 as later described. The lower yoke 18 is provided with two depending connecting-rods 37 whose lower ends are adapted to swing in a fore-andaft direction in the rear of the shaft 20, and. said shaft is provided with two radial arms 38 extending in about the same radial direction as the outside arms 35, said arms 38 being adapted to engage the shoulders39 on said connecting-rods for lifting up said yoke 18 as later described. This lower yoke 18 is provided centrally with one depending connectingrod 40 whose lower end is adapted to swing in a fore-and-aft direction in front of the shaft 20, and said shaft is provided with a radial arm 41 adapted to be engaged by a shoulder 42 on said connecting-rod and sup port said yoke for purposes later shown.

In the use of the machine, the parts are brought into the position shown in Figs. 1, 4, and 10. In this position, the shaft 20 stands with its outer eccentrics 23 at the upper part of their stroke, while the inner eccentrics 22 are at the lower part of their strokes, the handle 43 by which said shaft is revolved extending horizontally in the forward direction shown. This position of the parts places the lower yoke 18 at the lower end of its stroke, while at the same instant the upper yoke 16 is supported in its uppermost position by a cord or cable 44 which extends up over and is secured to a pulley 45. This pulley 4-5 is jonrnaled on a shaft 46 which is in turn journaled in bearings 47 on the cap 13 of the framework, said pulley being provided with a the press-chambers 15 are filled with the plastic material for forming the brick. Then, by releasing the engagement of the hook 49 with the pulley-handle 48, said handle is allowed to swing over into the position indicated by the dotted representations 48 in Fig. 4, thus allowing the yoke 16 to drop down into the position indicated by the dotted representations 16 in said figure. With the yoke 16 in this position, its pro jecting end lugs 28 are caught by the hooks 27 of the connecting-rods 25, and its depending plungers 1.7 have just entered the presschambers 15 on top of the charge of material to form the brick. It will be noted that at this instant, and while the handle 43 of the shaft 20 extends horizontally forward in the initial position previously referred to, the single arm. 41 of said shaft contacts its connecting-rod 40 above the shoulder 42 there on, so as not to engage said shoulder during the initial movement of said shaft and arm to therear. Now, by swinging the handle 43 of the shaft 20 up and over backward 180 degrees into the position shown in Figs. 2 and 5, the lower yoke 18 and its plungers 19 are force-d upward by the lifting action of the eccentrics 22 on the connecting-rods 24, while at the same time the upper yoke 16 and its plungers 17 are drawn downward by the outer eccentrics 23 and connecting rods 25; these movements bringing the parts into the position shown in Figs. 2, 5, and 11. It will be noted that at this instant the projecting arms 35 of the shaft 20 have also swung over backward, swinging the lower ends of the connecting-rods 34 backward and dropping under the shoulders 36 thereon; while the radial arms 38 of said shaft 20 have also swung over backward and have dropped under shoulders 39 on the depending connecting-rods 37 of the lower yoke 18. The hooked ends 27 of the connecting rods 25 are then forced out of engagement with the lugs 28 of the upper yoke by suitably manipulating the lever 30. Now, by raising the handle 43 of the shaft 20 back up into the nearly vertical position shown in Figs. 3 and 6, the arms 35 of said shaft rise upward on the connecting-rods of the upper yoke 16 and raise said yoke rapidly upward where its plungers 17 stand high above the press-chambers 15. This upward movement of the yoke 16 allows the pulley 45 to be revolved by the action of a tension spring 50 on its shaft 46 and thus take up the cable 44, the handle 48 of said pulley swinging into locking engagement with the hook 49 in position to support the yoke 16' in its uppermost position. While the upward movement of the upper yoke 16 is being produced by the action of the arms 35 on its connecting-rods 34, the lower yoke 18 is also being raised upward by the lifting action of the aforesaid arms 38 of the shaft 20 on the depending connecting-rods 39, thus lifting said yoke 18 rapidly upward where the upper ends of its plungers 19 will stand flush with the upper ends of the presschambers 15 or with the upper face of the casing 14. This upward movement of the lower yoke 18 and its plungers 19 raises the pressed and finished brick up where they may be removed from the machine. After removal of the brick, and during the further forward movement of the handle 43, the extreme lower ends of the connecting-rods 34 and 37 are limited in their forward swing ing movement by abutting the shaft 20, a further forward movement of said shaft by said handle 43 causing all of the arms 35 and 38 to trip out of lifting engagement with said connecting-rods. This allows the upper yoke 16 to remain supported by the cable 44 in the position shown in Figs. 3 and 6, and at the same instant allows the lower yoke 18 to drop downward until the shoulder 42' on the single connecting-rod 40 of said yoke abuts the end of the single arm 41 of the shaft 20. Then, by bringing the handle 43 of the shaft 20 down forward back into the initial position shown in Figs. 1 and 4, the lower yoke 18 is let slowly downward toward the initial position shown in said figures, the shoulder of the connecting-rod 40 slipping past the arm 41 just before the completed movement of said shaft and arm to initial position. With the parts in this position the machine is ready to be recharged or re-loaded with material for an other pressing of brick, and the handle 43 of the shaft 20 lies entirely down forward in the initial position shown in Figs. 1 and 4, preparatory to having the parts again operated as on the previous pressing.
